o ALL WHOM IT MAY conoizmv:

Be it known that 1, WILLIAM GLWATSON, of Paterson, in the county of Passaic, and State of New Jersey, have invented a new and improved Silk-Gleaner; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawi g forming part of this specification, in which- Figure 1 represents a front elevation of my invention.

Figure 2 is a'vertical transverse section of the same.

Figure 3 is a front elevation, showing a modification ofthe'same;

Similar letters of reference indicate corresponding parts,

This invention relates ten new device for cleaning silk while the same is being wound on bobbins, and conists,.first, in the use of horizontal instead of vertical'guides, whereby the lateral motion .of the thread as it is being wound spirally around the bobbin is accommodated. Theinvention alsoconsists iu the arrangement of the cutters or scrapers, which are made reversible; and consistsalso in the construction of the holder, which is such that when the thread is brought in contact with the upper edge of the holder, it will be guided between.

the cutters;

A represents the holder, made of cast iron or other suitable material, of the shape represented in fig. 1. Its shape is somewhat similar to thatpf a letter (i, supportedupon a post, a The upper arm of the G is horizontal, and is smoothed to receive the upper cleaner or knife B, which is screwed to the holder. The upper edge of the cleaner B rests against a flange, b, which is formed on the holder, as shown, so that the said. cleaner cannot be adjusted up and down. C is the" lower cleaner. The same is securedto the face of the holder. by means of suitable screws 0 c, fitting through .slots in the cleaner, as shown. Set-screws d d arranged in the lower part of the holder, are used toadjust the cleaner 0 up and d own,'so that the space between the cleaners maybe adapted to liner or coarser thread. The cnds-of the cleaner G project beyond those of the cleaner B,

as is clearly shown in fig. 2. Above one end of the cleaner 0 projects from the holder A, a post,-D-, as shown. The upper edge of the upper arm of the G-shapcd holder is inclined towards the post D, and ends with the end of the cleaner B, so that when the thread is placed upon the inclined rounded edge of the holder, it will slide down and will fell upon the cleaner C, the post D preventingits slippingolf the apparatus. The motion of the thread, as it passes from one end of the bobbin to the other, causes it to.move'in the slot between the cleaners, 4

and this apparatus will be of much greater valnethan those heretofore in use, in which the slots were vertical, as the thread will be able to move in the required plane, and will not be twisted and weakened by the apparatus.- The cleaner B can be reversed as well as the cleaner 0, so that when one edge is dull the other can be used, and thus all the four edges can be employed, while with the ordinary devices, only one edge of-each' cleaner could be used,-owing to the rounded guide corner of each cleaner. Fig. 3 represents a device in which my invention of using the horizontal cleaners is applied .with an ordinary set of cleaners, which may beadjusted up and down, but which cannot be reversed.

I claim as ne\v,,and desire to secure by Letters Patenta a 1, The horizontal frame A, provided with a curved guide A, post D, flange b, and stand a, all constructed and arranged substantially as and for the purpose set forth;

2. In combination with the above, I claim the fixed knife B, and adjustable knife C, wheh'said knives B and C are horizontally arranged and reversible, substantially as and for the purpose set forth.

3,, In combination with the frame A andknife C, I claim the adjusting-screwsd 01, substantially as set forth.

4. The silk-cleaner constructedsubstantially as described, and consisting of the frame having curved guides A, post I), stand a, and flange 6, fixed knife B, adjustable knife C, and screws (1 c, all arranged as set forth.

WM. G. WATSON.
